When you need to clean without grit, water or residue, dry ice blasting is in a class of its own. Goliath Coatings provides dry ice blasting across Auckland for electrical equipment, food-production lines, machinery and delicate surfaces where traditional abrasive media simply cannot be used.
Why dry ice blasting leaves no residue
Dry ice blasting fires solid CO2 pellets that sublimate — turn straight to gas — the instant they hit the surface. They lift contamination through thermal shock and kinetic energy, then vanish, leaving only the debris that was being removed. There is no secondary waste media to clean up, no water, and no abrasive grit to find its way into bearings or electronics.
Where dry ice blasting is the only option
We use it to clean electrical switchgear and motors without water, food and beverage equipment where grit and chemicals are unacceptable, printing and packaging machinery, moulds and tooling, and fire or smoke-damaged surfaces. Because it is non-abrasive and non-conductive, much of this work can be done in place without full disassembly.
Clean, contained and fast
Dry ice cleaning is often faster than stripping and hand-cleaning because there is no media clean-up and frequently no need to dismantle equipment. We assess the contamination and surface, then set the pellet size and pressure to clean thoroughly without damaging the substrate underneath.
What dry ice blasting achieves
Dry ice blasting fires recycled solid CO₂ pellets that sublimate on impact, lifting contaminant without abrading the surface underneath. Because the pellets turn straight to gas, there is no grit, no slurry and no secondary waste — only the dislodged material to collect. It is non-conductive and non-flammable, so we can clean machinery, electrical gear, food-production lines and moulds in place, often while equipment stays live. Ideal where you need cleaning without changing the substrate.

Dry ice blasting FAQs
Q: Does dry ice blasting leave any residue?
A: No — the CO2 pellets sublimate on impact, so the only thing left to remove is the contamination itself. No grit, no water.
Q: Can you clean electrical equipment with it?
A: Yes — dry ice is non-conductive and dry, so switchgear, motors and electronics can be cleaned in place without water damage.
Q: Is it safe for delicate surfaces?
A: Yes — it is non-abrasive, and we tune pellet size and pressure to clean without harming the substrate.
Q: Does dry ice blasting damage the surface?
A: No — it’s non-abrasive, so it removes the contaminant without changing the profile underneath, and leaves no grit or water behind. That’s why it suits machinery, electrical and food-plant cleaning.
